safe to update?

Hey everyone,

I am very new to the wii. I just got my wii in the mail today and it came with a drivekey installed. I have 3.1U as my firmware. I have been reading about 4.2 and how it disables some games, so I don't think I want to upgrade to 4.2. But if i run system update, would 4.1 be installed prior to 4.2 or would my wii just download 4.2?

As i said, i'm very new to the wii, so I am starting to learn the terms. So if i sound confused, I am I am starting off reading about homebrew. if anyone have any suggestions on what I should be doing and looking at as a new wii owner with drivekey.. I would be very greatful. This forum has a lot of information and I am starting to look at them.
